EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.6 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 75% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, OAuthTokenStore reads caller-supplied token identifiers from the shared Core Token Store (CTS) without an OAuth-only namespace, and OAuthAdapter accepts a row whose BLOB claims to contain an OAuth token without binding the trusted CTS type or verifying integrity. An attacker who can place controlled JSON in CTS under a known token identifier, such as through Push Registration followed by an anonymous SNS callback in an enabled realm, can mint OAuth bearer tokens and OpenID Connect ID tokens with chosen subject, client, realm, and scope. The flaw does not by itself create an OpenAM SSO session or grant console access. This issue is fixed in version 16.1.1.
